Then, while each instrument holding frame 20 is disposed on the front side of the wall material W, only each instrument mounting frame 11 is disposed on the back side of the wall material W, and the instrument mounting frame 11 is attached to the wall material W by screws 23. Supported on the back side.

  Subsequently, as shown in FIG. 3 and FIG. 4, on the back side of the wall material W, the contact surface 12 a of each instrument mounting frame 11 is brought into contact with the back surface of the wall material W, and the adjacent second regulating protrusion 182. The first restricting protrusions 181 are inserted into the plurality of rows of wall holes Wa while abutting the abutting portions 182a. In the upper first restricting protrusion 181, the right first restricting protrusion 181 has an upper surface in contact with the upper surface Wa <b> 1 of the plurality of rows of wall holes Wa and a right end adjacent to the upper surface Wa <b> 1. Abuts on Wa3. The first regulation protrusion 181 on the left side is in contact with the upper side surface Wa1 of the plurality of rows of wall holes Wa, and the left end is in contact with the left side surface Wa4 adjacent to the upper side surface Wa1.

  In the lower first restricting protrusion 181, the lower face of the first restricting protrusion 181 on the right side is supported by the lower surface Wa <b> 2 of the plurality of rows of wall holes Wa, and the right end is on the lower surface Wa <b> 2. It abuts on the adjacent right side surface Wa3. The lower surface of the first left restricting protrusion 181 is supported by the lower surface Wa2 of the plurality of rows of wall holes Wa, and the left end thereof is in contact with the left surface Wa4 adjacent to the lower surface Wa2.

  In the state where the first and second restricting protrusions 181 and 182 are inserted into the wall holes Wa, the lower first and second restricting protrusions 181 and 182 are formed on the lower side surface Wa2 of the plurality of rows of wall holes Wa. As a result, the two instrument mounting frames 11 are positioned on the multiple-row wall material W. In this positioning state, the opening 15 of the instrument mounting frame 11 faces the front side of the wall material W from the plurality of wall holes Wa, and the screw hole 19 also faces the front side of the wall material W from the plurality of wall holes Wa. It is out.

  Furthermore, as shown in FIG. 4, each claw piece 17 a of the upper locking projection 17 is engaged with the upper side surface Wa <b> 1 of the plurality of rows of wall holes Wa and locked, and the lower locking projection 17. Each claw piece 17a is engaged with the lower side surface Wa2 of the plurality of rows of wall holes Wa to be locked. Then, the locking of each claw piece 17a restricts both the instrument mounting frames 11 from falling to the back side of the wall material W. As shown in FIG. 3, in the state where the two instrument mounting frames 11 are positioned, a pair of upper and lower screw holes 19 are arranged in two rows on the left and right sides, and between the left and right screw holes 19. The pitch P is a pitch between the wiring devices H arranged in a plurality of rows.

  Subsequently, a screw 23 screwed into the upper nut is further screwed into each instrument mounting frame 11. Further, the screw 23 is inserted into the lower insertion hole 22 of each instrument holding frame 20, and the screw 23 is screwed into the nut of the lower screw hole 19 of each instrument mounting frame 11. When both the screws 23 are tightened, the both appliance holding frames 20 are drawn to the wall material W as the screws 23 are screwed into the nuts, and as shown in FIG. 6 and FIG. The wall material W is sandwiched between both the sandwiching pieces 13 and the upper and lower parts of the instrument holding frame 20. When the screw 23 is screwed into the nut, the wiring device H is installed on the front side of the wall material W, so that the device mounting frame 11 is installed on the back side of the wall material W. At this time, the contact surface 12a of the frame main body 12 contacts the peripheral edge of the plurality of rows of wall holes Wa on the back surface of the wall material W.

Next, the operation of the instrument mounting frame 11 will be described.
As shown in FIG. 3, in the state where the two instrument mounting frames 11 are abutted and the first and second restriction protrusions 181 and 182 are inserted into the plurality of rows of wall holes Wa, the four first restriction protrusions 181 are formed. The four inner side surfaces Wa1 to Wa4 of the plurality of rows of wall holes Wa come into contact with each other. For this reason, even if the force which moves to the two instrument attachment frames 11 in any direction of up and down, right and left acts, the 1st control protrusion 181 contact | abuts to inner side surface Wa1-Wa4 ahead of a moving direction. The movement of the two frame bodies 12 in the vertical and horizontal directions is restricted. As a result, the instrument mounting frame 11 is positioned at a position where the opening 15 and the screw hole 19 face the front side of the wall material W.

  Furthermore, in a state where the four first restricting protrusions 181 are in contact with the inner side surfaces Wa1 to Wa4 of the plurality of rows of wall holes Wa, the pitch P between the left and right screw holes 19 is the same as the pitch between the wiring devices H. Are aligned. For this reason, when the screw 23 is screwed into the nuts of the two fixture mounting frames 11, two rows of wiring fixtures H are installed on the wall material W at a predetermined pitch.

According to the above embodiment, the following effects can be obtained.
(1) In the instrument mounting frame 11, the first and second restricting protrusions 181 and 182 are provided on the front surface of the frame main body 12, and the abutting part 182 a is formed on the second restricting protrusion 182. Then, the two instrument mounting frames 11 are arranged on the back side of the wall material W, and the contact portions 182a are brought into contact with each other while the first and second restriction protrusions 181 and 182 are inserted into the plurality of rows of wall holes Wa. Then, the screw holes 19 arranged on the left and right sides of the two appliance mounting frames 11 are arranged so that the pitch P is the same as the pitch for installing the wiring appliance H. Therefore, the pitch P between the screw holes 19 can be adjusted only by abutting the abutting portion 182a. Compared with the case where the pitch P is adjusted by moving the instrument mounting frame 11, the instrument mounting frame 11 is simpler. Can be aligned.

  (2) In the instrument mounting frame 11, first and second restricting protrusions 181 and 182 are provided on the front surface of the frame body 12. Then, when the first and second restricting protrusions 181 and 182 are inserted into the plurality of rows of wall holes Wa, the first restricting protrusion 181 comes into contact with the four inner side surfaces Wa1 to Wa4 of the plurality of rows of wall holes Wa, The opening 15 of the instrument mounting frame 11 can be positioned at a position facing the plurality of rows of wall holes Wa. Therefore, the instrument mounting frame 11 can be positioned simply by inserting the first and second restricting protrusions 181 and 182 into the plurality of rows of wall holes Wa and bringing the abutting parts 182a into contact with each other. Can be easily performed.

  (3) In a state where the contact surface 12a of each instrument mounting frame 11 is in contact with the back surface of the wall material W, the first and second restricting protrusions 181 and 182 are located in the plurality of rows of wall holes Wa, Since it does not protrude to the front side of the wall material W, it is not necessary to bend or break the first and second restricting protrusions 181 and 182 in the plurality of rows of wall holes Wa. Therefore, the positioning operation of the instrument mounting frame 11 is completed simply by inserting the first and second regulating protrusions 181 and 182 into the plurality of rows of wall holes Wa while bringing the contact surface 12a into contact with the back surface of the wall material W. Thus, the positioning operation can be easily performed.

  (4) The frame body 12 is formed in a U shape from a pair of sandwiching pieces 13 and a connecting piece 14 that connects one end of the sandwiching piece 13 in the long side direction. For this reason, even if the contact portions 182a of the two instrument mounting frames 11 are brought into contact with each other, a part of the instrument mounting frame 11 does not cross the vicinity of the center in the plurality of rows of wall holes Wa. Therefore, even if the two appliance mounting frames 11 are arranged on the back side of the wall material W, the appliance mounting frames 11 do not hinder the installation of the wiring appliance H.

  (5) When the wiring device H is installed using the single-row wall holes Wb, the first restriction protrusions 181 and the second restriction protrusions 182 come into contact with the four inner side surfaces Wb1 to Wb4 of the single-row wall holes Wb. The instrument mounting frame 11 is positioned.
